A sample resulting from a sampling plan that can be expected to adequately reflect
the properties of interest of the parent population. A representative sample may be
a random sample
or, for example, a stratified sample
, depending upon the objective of sampling and the characteristics of the population.
The degree of representativeness of the sample may be limited by cost or convenience.
